Patent CA-2300672-A1 (CA)
Inventor: CASO GREGORY S
IPC: H04B7/185
Filed: 2000-03-14
Abstract: The present invention provides a method and apparatus for mitigation of false co-channel uplink reception, also known as show-thru. The method includes the steps of selecting a scrambling sequence A and selecting a scrambling sequence B differing from the scrambling sequence A. The method then applies (408) the scrambling sequence A to uplink A data to form scrambled uplink A data and applies (410) the scrambling sequence B to uplink B data to form scrambled uplink B data.  The uplink A data and the uplink B data are thereby differentiated and have vastly improved resistance to show-thru. The scrambled uplink A data and the scrambled uplink B data are then transmitted (412, 414) to a receiver, for example, onboard a satellite. The also codes (404, 406) the uplink A data and the uplink B data prior to scrambling. The coding (404, 406), in general, applies an error correcting code capable of correcting T errors. The method is generally applicable to numerous same color uplink beams in a coverage area. In applying the scrambling sequences to the uplink data, the method may use an exclusive-or operation. In applying the coding, the method may use a Reed-Solomon code, and in particular a (236, 212) Reed-Solomon code (T=12) particularly suitable for 53-byte Asynchronous Transfer Mode (ATM) cells. No extra uplink data is added with the exclusive-or operation and only a minimal additional processing step is used before transmission.      Furthermore, the method is compatible with established error correcting coding techniques, for example, Reed-Solomon decoding.

Title: Measuring fish tape
Inventor: FRIESEN GEOFFREY
IPC: H02G1/08
Filed: 2000-03-22
Abstract: A commonly used tool in the Electrical Industry is a "fish tape" (protected under patent #US04092780) which is a long rectangular spring steel wire used for pulling wire conductors through conduit (pipe) for mechanical protection.      In many cases the electrician must know; to some degree of accuracy how long the conduit run is in order to cut an appropriate length of conductor or to know how much conductor to purchase. This can be a tedious and time consuming task with a tape measure especially in situations where the conduit is concealed either by a wall, ceiling, or under a poured cement floor. In this invention units of measurement are impressed onto the fish tape for an efficient and confident conductor length, thus saving the electrician time and eliminating the risk of excess waste.

Abstract: The multipart dowel is inserted into a hole. In one embodiment, the multipart dowel for a removable anchor which is provided with an anchor pin and devoid of any threading is designed as a heavy load anchor consisting of a dowel sleeve (1,2) and an expandable body (1,3) which rests with a collar (1,5) on the opening (1,6) of the dowel on top of the dowel sleeve (1,2) and blocks the heavy load anchor pin (1,1) against unwarranted loosening. The dowel sleeve (1,2) is anchored inside the hole by means of teeth and has several successive annular rings on the inside (1,8). The annular rings (1,9) of the expandable body situated on the outer wall of said body (1,3) are located opposite to the annual rings of the dowel sleeve. The annular rings (1,9) of the expandable body are embodied in such a way that when the expandable body is displaced in relation to the dowel sleeve (1,2), pressure forces act upon the heavy load anchor pin (1,1) and the hole. Rotating clamping bodies (1,11) are inserted into the free spaces (1,10) that are formed between the rings. In another embodiment, the multipart dowel protects the anchor pin (2,1) from unwarranted loosening by means of wedging and provides support to a groove (2,4) in the inside wall of the outer dowel sleeve (2,2) which fits into the hole, whereby said groove has slanted edges (2,6, 2,11) pointing away from the opening (2,5) of the hole, forming slanted planes from the opening (2,5) of the hole onwards.

IPC: F21K2/00

Abstract: A photoluminescent light emitter has higher surface luminance and lumimous exitance characteristics as compared with those of current photoluminescent light emitters. The light emitter may be implemented without the use of refractive elements and has high surface luminance characteristics in substantially all viewing directions. This performance is accomplished by substantially increasing the effective surface area of the photoluminescent material from which the reradiated light is emitted through controlled texturing of the exposed photoluminescent surface. Photoluminescent material with a textured surface emits a portion of light that is incident upon the surface and does not propagate immediately into the environment. Upon reflection by the textured surface, this light is added to the emitted light and thereby increases the measurable luminance of the exposed photoluminescent surface. Certain embodiments take advantage of the self-excitation properties of certain photoluminescent pigments in which the spectrum of the emitted light overlaps the spectrum of the excitation light. Some of the emitted light incident upon the textured surface is absorbed rather than reflected. Of this light, some of its energy excites the photoluminescent pigments rather than being converted to thermal heat energy. This absorbed energy is later reradiated as light within the emission spectrum of the pigments, thereby further increasing the overall luminous exitance of the photoluminescent materials.

Title: Method and apparatus for controlling reverse link interference rise and power control instability in a wireless system
Inventor: THOMAS MATHEW
IPC: H04B7/26
Filed: 2000-10-03
Abstract: A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when E b/N o measurements for served mobiles do not meet target E b/N o levels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target E b/N o levels in a centralized manner based on an overall system state so that only a limited number of target E b/N o levels are allowed to increase when frame erasures occur. By preventing a percentage of target E b/N o level increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.
